.... it makes; at the current point of sophistication, a high degree of interactivity and added communication channels to the system is arguably a better tool for raising system usefulness than adding functionality or intelligence to the existing channel, be it text, speech, or a rule based system [9, 15, 19]. As indicated in the previous section, in DIVERSE we make use of the errors do notmatter principle to the extent that we will not worry about the system misinterpreting the occasional user utterance: as long as the interface is interactive we do not expect misinterpretations to be too crucial a ....

.... it makes; at the current point of sophistication, a high degree of interactivity and added communication channels to the system is arguably a better tool for raising system usefulness than adding functionality or intelligence to an existing natural language channel (Chandrasekar and Ramani, 1989; Lemaire and Moore, 1994; Karlgren et al. 1995) An advantage of making the agent s focus explicit is that it reduces the need for the system to reason about what the user believes about the agent s competence instead the system can assume that users will make use of the focus list as the point of departure when ....

....just the most recent one. Our history representation, by comparison, captures the relationship between both actions and communications (including questions) and the goals to which they contribute, making possible much more powerful intelligent assistance and transformations. In Moore et al. s work [7, 12], which focuses on explanation dialogues, users are presented with a full textual history of their interaction with the system, from which they may select any phrase as the context for a further query. Unlike our approach, Moore s history display has no explicit structure other than the ....

However, most work on applying human discourse principles to human computer interaction, e.g. Lambert and Carberry, 1991; Yanklovich, 1994) have assumed that natural language understanding will be applied to the user s utterances In Moore et al. s work (Lemaire and Moore, 1994; Moore and Swartout, 1990) which focuses on explanation dialogues, users are presented with a full textual history of their interaction with the system, from which they may select any phrase as the context for a further query.

.... people serving as the basis for a much wider range of collaborative activities [Twidale, Nichols and Paice, 1996] Such a search object can be stored, high lighted, edited, annotated, replayed and re executed: typically the kinds of activities that occur in tutorial and helpgiving interactions [Lemaire and Moore, 1994]. Figure 1 The Ariadne interface The Ariadne Interface We have developed a prototype interface, Ariadne, which attempts to support these activities. Ariadne runs on top of an OPAC or online database, recording the queries and their results and then producing a visualisation of the search ....

....forthcoming) 3 Interaction Principles of the POP Prototype The knowledge acquisition phase has been intertwined with the design and development of a prototype help assistant, the POP (PUSH Operational Prototype) system. The basic interaction mechanism of POP combines navigation and search (Lemaire et al. 1994) through a hypertext space. Navigation is mainly realised through direct manipulation, by pointing and clicking in a graphic representation of the information space or in hypertext fragments. Users can pose 5 search questions by clicking on hotwords (Kobsa et al. 1994) marked bold in the text, ....

....in POP) but also by entering a query in free text form. In addition to the means for search and navigation in the domain information, the interface also provides a topic oriented dialogue model, where previous queries and topics are always visible in a directly accessible dialogue history (Lemaire and Moore, 1994). In figure , we see the current interface of POP with its division into one dialogue history window, one textual input output window and two graphical windows. This basic interaction structure allows users to navigate and search through the database. However, the empirical investigations point ....
